Product Introduction

The PLS series vertical impact crusher utilizes mutual impact for self-crushing, or materials are crushed by striking against metal反击 plates. This machine features two types of crushing chambers: "stone-on-stone" and "stone-on-iron." The "stone-on-stone" chamber is primarily used for crushing hard materials, while the "stone-on-iron" chamber is more suitable for medium-hard materials. Importantly, the structures of these two chamber types can be easily interchanged, allowing the machine to adapt seamlessly to the specific needs of different materials during the crushing process.

The PLS series is widely used in the crushing and coarse grinding of metallic and non-metallic ores, as well as for applications in highways, water conservancy and hydropower projects, refractory materials, abrasives, glass-ceramic raw materials, construction aggregates for urban buildings, manufactured sand and gravel, and various metallurgical slags. It particularly excels in processing medium-hard, extra-hard, and abrasive materials such as silicon carbide, carborundum, sintered alumina, and magnesia sand—outperforming other types of crushers in these demanding applications.

Maximum feed size: 30–60 (mm)

Production capacity: 24–715 (t/h)

Application Areas

The PLS vertical impact crusher is widely used in artificial sand-making operations across industries such as hydroelectric power, refractory materials, construction, high-grade highways, and railways.

Applicable Materials

The PLS vertical impact crusher is particularly advantageous over other types of equipment when handling medium-to-hard, extra-hard, and corrosive materials such as granite, basalt, diabase, and sandstone. In the field of artificial sand production, its crushing capacity far surpasses that of comparable products, making it the ideal choice for artificial sand-making equipment today.

How it works

The PLS series vertical impact crushers employ two distinct crushing mechanisms—“stone-on-stone” and “stone-on-iron”—depending on the operating conditions and the material being crushed, as well as how the feed is controlled. In the “stone-on-stone” mode, a waterfall-style feeding system is used to divide the incoming material into two streams in a precisely controllable manner. One stream enters the horizontal rotor chamber through the central feed pipe at high speed, while the other stream flows downward via multiple overflow ports around the feed hopper, eventually landing inside the rotor cavity. The material entering the rotor is rapidly accelerated by the high-speed rotation of the impeller and then ejected outward through three or more discharge outlets. As this material collides violently with the descending particles falling from the overflow ports within the rotor’s peripheral zone, it undergoes intense self-impact, resulting in the "stone-on-stone" crushing process. In the “stone-on-iron” mode, all the incoming material is fed directly into the high-speed rotating rotor chamber via the central feed pipe. After being accelerated by the rotor’s rapid spin, the material is forcefully discharged through three or more emission ports, where it violently strikes the metal impact plates mounted along the inner walls of the crusher’s crushing chamber, thus creating the "stone-on-iron" crushing mechanism.

Product Features

1. This sand-making machine can be optionally equipped with a manual hydraulic pump, allowing precise adjustment of the impeller's feed rate. Combined with the adjustable height position of the distribution disc, this feature enables accurate control over the ratio between the impeller feed and the material cascading around the circumference.

2. This sand-making machine can also be optionally equipped with a suspended manual or electric hoist, allowing for easy lifting of components such as the machine’s upper cover, feeding hopper, distributor, impeller, and spindle during equipment inspection and maintenance—quickly and conveniently.

3. The machine's upper cover can be optionally equipped with a hydraulic lifting and opening device, allowing the feed hopper to be easily lifted, rotated, and moved aside during equipment maintenance.

4. This sand-making machine features a switchable crushing mode—either "stone-on-stone" or "stone-on-iron"—allowing it to adapt to a wider range of operating conditions and meet the diverse shaping and crushing requirements of different materials.

5. This sand-making machine can also be optionally equipped with a稀油 lubrication system and a PLC-based automatic control and monitoring system, enabling real-time monitoring of functions such as feed rate, current, oil temperature, spindle temperature, and vibration protection.

Note:

1. When operating in crushed sand-making mode, the linear velocity is 70 m/s, with a minimum throughput corresponding to the impeller running at full load without any diversion, and a maximum throughput equal to the impeller at full load plus a 30% diversion rate.
2. The linear velocity during the high-speed fine-crushing and shaping mode is 80 m/s.
